The stars of Cassiopeia (the “W” at centre) and the other stars of the summer and autumn sky reflected in the still waters of Emerald Lake, in Yoho National Park, BC. Vega is at top, Deneb below it, while the stars of Perseus and Pegasus are just rising. The sky is blue from the glow of perpetual twilight that lights the sky all night at this latitude in June and early July. This was June 6, 2016. High haze fuzzes the stars naturally here. This is a vertical panorama of 4 segments, taken with the iPano unit, and with each segment a 30-second exposure at f/2.2 with the Sigma 24mm Art lens and Nikon D750 at ISO 4000. Stitched with Adobe Camera Raw.
Mars (brightest) and Saturn (to the left), in the evening twilight at Moose Meadows on the Bow Valley Parkway, Banff, Alberta, June 4, 2016. They shine above Pilot Mountain. This is a stack of 5 x 8-second exposures for the ground (mean combined to smooth noise) plus a single 8-second exposure for the sky, untracked, all at f/2.5 with the 35mm lens and Canon 6D at ISO 800.
